ENTSOG TYNDP 2017 - Annex C4 - Demand Methodology

2.4.3 Own Data assumptions

Application of the Thermal Gap approach was the default selection of the Power Generation Methodology, in order to both achieve consistency with the ENTSO-E TYNDP 2016 Vision data whilst still reflecting the assumptions of the ENTSOG sce- narios. However, TSOs could submit their own data, to reflect the fact that ENTSOG was not involved with the development of the scenarios for the electricity TYNDP 2016. As- sumptions were provided by gas TSO and used as an early basis for feedback to EN- TSO-E for future collaboration. As discussed earlier in this methodology, TSOs were encouraged to provide own data for high demand cases, but thermal gap or ENTSO-E data could be used if TSOs couldn’t provide their own data. Data provided by TSO was subject to validation against potential generation from ENTSO-E capacities and the thermal gap approach to ensure consistency in the alignment of the scenarios and visions.
